K I

In order to vary the amount of feed of the roll gold, the upper ends of the rods 50 and 51 are provided for horizontal adjustment in the slots 54 and 55' in the rocking lever 52. Likewise the lower end of the rod 50 is providedfor horizontal adjustment in the slot 56 in the'lever 47. The, lower end of the ro dO is also provided with a, slot .57 in order to provide a certain amount oflost motion between this rod and the lever.

This lost motion is an important feature of the device since it prevents'any-feeding or Vmovement of the roll gold during the first movement upwardly of the head after'the stamping operation. his very important that there be no sliding or dragging of the 1 roll gold across the work or the type. Consequently, after the stamping operation there must be no feeding ofthe roll gold until the head has been raised "a short distance and the roll gold lifted from the work and also removed out of contact with the typeby the relative downward movement of the rods 38.

' After this has been accomplished, further upward movement of the head'causes the lever 47 to rock'downwardly and feed the roll gold as above described. j The exact distance to which theroll gold is'to be fed is determined by the adjustment of the' upper ends of the rods 50, 51 in the slots 54, '55 and by adjustment of thelower end ofthe rod in the slot 56 as above described. j While I have shown and described certain embodiments of my invention, 'it is tobe understood that it is capable of many modifications.
